Antibiotics currently help fight bacterial infections both in people and livestock, saving countless lives. However, constant use of these drugs has now bred germs resistant to many antibiotics — superbugs that some experts warn could lead to apocalyptic scenarios. Scientists at the Centers for Disease Control and Prevention have estimated that each year in the United States, nearly 2 million patients acquire infections in hospitals. Many of these infections are caused by these drug-resistant contagions.

Scientists are hunting for ways to overcome drug-resistant bacteria, such as viruses known as bacteriophages, which infect and kill only bacteria. Now investigators suggest predatory bacteria that eat other bacteria may serve as vital allies, too. Read More
